How much of a difference did it make? Satisfied? Total cost?

Total cost and how did you tune it? Does everything still work?

It does make a big difference but you do not end up with a sport car. Torque increases a lot.

cost was around $8.5k through TREperformamce

satisfied yes, but it did take 5 different tunes to get the car ready and I had to get an MDI2 to fix the imobilizer (both TRE and Procharger where lost about that).

$8.5k

PCM was sent to HP Tuners, they unlock it and send it back, then ProCharger sends the tune files and you load them through your pc.
I shipped it on a Monday, arived to HP tuners on a Wednesday and they shipped it back on a Friday aternoon.

Absolutely everything works. But the car will not start at the first press of the start engine (starts at the second press). You need to take if yo someone (dealer, mechanic, yourself) with an MDI2 tool and SPS suscription. I did it myself and I am not a mechanic. My local dealer sucks and was lost on what needed to be done.

Did you have to upgrade any of the engine internals, or can you just slap the supercharger on it and tune it?

No need to upgrade anything. No drilling required.
the supercharger bolts on on existing places. It only adds 8psi which is low, but they claim +50% hp. I have not taken it to a Dyno.

I did change the sparkplugs which are not included in the kit and you find out they are “highly recommended” after you are installing. They make the engine behave better (idle, etc)

I'm glad to see somebody finally install one. I had a supercharger on my last two trucks. It would be cool if a lt4 charger could be made to fit the T1.

Did you need to do the hood scoop for this? Also how do you like the bd light bar?

The scoop is just because I like the way it looks. It may be removed anytime. It installs with a strong double sided tape

the light bar is a must for these trucks. The original hi-low beam is very bad.
I did install the switch on the right side, which I feel is much easier to reach while driving:
